vanadium dioxide, special properties
semi conductor
heat passes throught ill certain temperature
at certain temp, reflects heat.
Adding stuff like tungsten can change the temp.
Ex. 1.9% tungsten – reflect at 84 F
Contact with beryl turns green, making an emerald.

vanadium is a metallic element
the symbol for vanadium is "V"
is a part of the transition elements in group five
element number 23
vanadium melts at the temperature of 1890 degrees C (3434 degrees F)
vanadium was discovered in the year 1801, by a Mexican man, Andres
Manuel de Rio
at first, vanadium was mistaken as chromium because it has similar
properties and characteristics
so vanadium was rediscovered and recognized as it own element in about
1830, by a Swedish chemist named Nils Gabriel Sefstrom
vanadium is a silver-white metal
it is also one of the hardest metals of them all
vanadium is soluble in nitric and sulfuric acids, and insoluble in hydrochloric
acid, dilute sodium hydroxide, and dilute alcohol
vanadium has the ability to form several different types of acidic oxides, a few
of the most important being the dark green trioxide and the orange
pentoxide
Jeff Clement and Evan Udelsman
 some other very important compounds that vanadium is included in are,
vanadium monosulfide, vanadium dihydroxide, and metavanadic acid
 vanadium is the nineteenth element in abundance of the earths atmosphere
 it hasn’t been found pure or alone yet, but it is found combined with other
metals
 in the early 1980s, the united states exported about twelve percent of the
worlds annual amount of vanadium. Russia and South Africa also exported
large amount of vanadium
 vanadium is used in many alloys because of its hardness and great tensile
strength
 some alloys that vanadium is found in are, nickel vanadium and chromevanadium
 chrome- vanadium metal are very useful, they are used in springs, gears, and
many engine parts
 titanium-vanadium alloys are also often used, they are used for some things
such as missile cases, jet-engine containers, and nuclear reactors
components
 vanadium has replaced platinum as a the most used metal used for the
manufaction of sulfuric acid
 vanadium is also widely used for the development of photographs
 another common use is a drier in various paints

 Wind is the fastest growing source of energy in the US after natural gas.
 according to the World Watch Institute, wind power grew about the equivalent
of 104 power plants (enough power to serve 5.2 million US homes)
 as of december 2006, total world wide wind capacity was at 74 gigawatts
 wind power is also an energy source that doesn’t emit any green house gas
emissions
 now, experts are looking into vanadium redox-flow batteries (VRBs)
 VRBs can make wind power grow to the next level by increasing the tier
capacity
 there are already power plants using the assistance of VRBs, in Vancouver
and British Columbia
 also, as of May 2007 it has been announced that the Australian government is
investing AUS$1.83 million dollars (1,553,536 US dollars) towards the
deployments of VRBs in remote communities across the nation
 The invention of the VRB occurred at the University of New South Wales, in
the early 1980s
 the VRB battery has the ability to store large amounts of energy for a small
price, this is why the Vanadium redox-flow battery is so helpful
 on king island, VRBs have boosted wind power from 12% to 40% fo the total
populations power
 it has also reduced net diesel emissions by about 46% (or 2000 tons
annually)
 the VRBs most toxic component is the sulfuric acid in the electorlyte, but this
is only one third as acid and harmful as the lead-batery and other batteries
Jeff Clement and Evan Udelsman
 VRBs are unusable for cars though (for now)
 vanadium has a very low toxicity rate, so it doesn’t have a strong
environmental foot print
 new car batteries still in the invention process will almost double the wattage
power of a current hybrid car battery
 there are too many variables to calculate the money saved by the energy
stored by new VRBs, but there will be a decrease in cost
 wind and VRBs have the potential to provide the majority of all electrical
consumption
 VRBs will reduce the dependency on fossil fuels and other climate concerns
 VRBs can save the world just in time
Thwaities, Tim. "A Bank For the Wind." MAS Ultra- School Edition: New Scientist,

 with vanadium being used in VRBs, we can store large amounts of energy and
use it only when we need it
 King Island uses VRBs as a main resource for power
 King Island doesn't receive any energy from the main land (Australia), so the
island relies on their own wind farm for energy
 King Island also recently received (2003) and installed a new lartge
rechargeable battery, that stores unused wind energy to save as much wind
as possible and none goes to waste
 this new rechargeable battery saves a lot of money and at least 2000 tons of
carbon dioxide emissions
 A VRB (redox-flow battery) also can expand storage capacity, and a cheap
cost
 oil and coal companies receive a greater demand for electricity in different
parts of the year, like winter. But with a flow battery, extra electricity power
saved up from the summer can be used in the winter
 and with fossil fuels, supply and demand is hard to keep up with and satisfy,
this can be seen with today’s gas prices
 flow batteries also seem to have the ability to satisfy a broad range of
electricity needs. (small needs in the summer to large needs in the winter)
 installation of this new flow battery on King Island took place in the 1980s,
and it was installed by an Australian chemical engineer, Maria Skylla-Kazacos
 VRBs were invented in the University of New South Wales, but they are now
being produced and sold by VRB Power Systems in Vancouver, Canada
 flow batteries are more expansive than other batteries currently being sold,
but flow batteries will ultimately cost less, with the amount of energy that
doesn’t go to waste
 and flow batteries might run cheaper is they begin to become more popular
 VRBs are also being used in electric cars, with this, drivers one day can fill
their cars up with energized electrolytes, and the spent solution can be
recycled
